History

Formerly known as Sylpheed-Claws, it started in April 2001 as the development version of Sylpheed, where new features could be tested and debugged, but evolved enough to now be a completely separate program. It forked completely from Sylpheed in August 2005.

Features

Claws Mail provides many features,[2] among them are:

Limitations

Claws Mail is unable to send HTML mail. This is intentional. According to the developers, this decision has been made after a discussion, although no details are given.[5] It is still possible to receive HTML mail using Claws Mail.

Plugins

Claws Mail's features can be extended with plugins,[6] such as

Comparison of feed aggregators

The following is a comparison of RSS feed aggregators. Often e-mail programs and web browsers have the ability to display RSS feeds. They are listed here, too.

Many BitTorrent clients support RSS feeds for broadcatching (see Comparison of BitTorrent clients).

With the rise of Cloud computing, some cloud based services offer feed aggregation. They are listed here as well.

Enigmail

Enigmail is a data encryption and decryption extension for Mozilla Thunderbird and the SeaMonkey internet suite that provides OpenPGP public key e-mail encryption and signing. Enigmail works under Microsoft Windows, Unix-like, and Mac OS X operating systems. Enigmail can operate with other mail clients compatible with PGP/MIME and inline PGP such as: Microsoft Outlook with Gpg4win package installed, Gnome Evolution, KMail, Claws Mail, Gnus, Mutt. Its cryptographic functionality is handled by GNU Privacy Guard.

In their default configuration, Thunderbird and SeaMonkey provide e-mail encryption and signing using S/MIME, which relies on X.509 keys provided by a centralised certificate authority. Enigmail adds an alternative mechanism where cooperating users can instead use keys provided by a web of trust, which relies on multiple users to endorse the authenticity of the sender's and recipient's credentials. In principle this enhances security, since it does not rely on a centralised entity which might be compromised by security failures or engage in malpractice due to commercial interests or pressure from the jurisdiction in which it resides.

Enigmail was first released in 2001 by Ramalingam Saravanan, and since 2003 maintained by Patrick Brunschwig. Both Enigmail and GNU Privacy Guard are free, open-source software. Enigmail with Thunderbird is now the most popular PGP setup.Enigmail has announced its support for the new "pretty Easy privacy" (p≡p) encryption scheme in a joint Thunderbird extension to be released in December 2015. As of June 2016 the FAQ note it will be available in Q3 2016.Enigmail also supports Autocrypt exchange of cryptographic keys since version 2.0.

Flipboard

Flipboard is a news aggregator and social network aggregation company based in Palo Alto, California, with offices in New York, Vancouver and Bejiing. Its software, also known as Flipboard, was first released in July 2010. It aggregates content from social media, news feeds, photo sharing sites and other websites, presents it in magazine format, and allows users to "flip" through the articles, images and videos being shared. Readers can also save stories into Flipboard magazines. As of March 2016 the company claims there have been 28 million magazines created by users on Flipboard. The service can be accessed via web browser, or by a Flipboard application for Microsoft Windows and macOS, and via mobile apps for iOS and Android. The client software is available at no charge and is localized in 21 languages. Its current headquarters is located at 735 Emerson St, Palo Alto, CA 94301, recently moving from a nearby building.

Dictionaries for it are available for about 70 languages. The primary maintainer is Kevin Atkinson.

GNU Privacy Guard

GNU Privacy Guard (GnuPG or GPG), a free-software replacement for Symantec's PGP cryptographic software suite, complies with RFC 4880, the IETF standards-track specification of OpenPGP. Modern versions of PGP are interoperable with GnuPG and other OpenPGP-compliant systems.

GnuPG is part of the GNU Project, and has received major funding from the German government.

List of software forks

This is a list of notable software forks.

MH Message Handling System

The MH Message Handling System is a free, open source e-mail client. It is different from almost all other mail reading systems in that, instead of a single program, it is made from several different programs which are designed to work from the command line provided by the shell on Unix-like operating systems. Another difference is that rather than storing multiple messages in a single file, messages each have their own separate file in a special directory. Taken together, these design choices mean that it is very easy and natural to script actions on mail messages using the normal shell scripting tools.

A descendant of MH continues to be developed under the name of nmh.

News360

News360 is a personalized news aggregation app for smartphones, tablets and the web. It attempts to learn a user's interests by analyzing their interaction with news stories on the app and using semantic analysis and natural language processing to create an Interest Graph and construct a unique feed of relevant content for each user. The app has an audience of more than 4M users and is located in San Francisco, CA, with offices in Vancouver, BC and Moscow, Russia.Initially released for iPhone in late 2010, News360 is now available for all major mobile platforms, with versions for the iPad, iPhone, Android, Windows 8, Windows Phone and the web.

Prismatic (app)

Prismatic was a social news curation and discovery application for various Web browsers and mobile devices running iOS. It combined machine learning, user experience design, and interaction design to create a new way to discover, consume, and share media. Prismatic software used social network aggregation and machine learning algorithms to filter the content that aligns with the interests of a specific user. Prismatic integrated with Facebook, Twitter, and Pocket to gather information about user's interests and suggest the most relevant stories to read.

Prismatic initially launched in 2012 for Web browsers and the iPhone, followed by the release of an iPad app on December 19, 2013.On December 20, 2015 the company closed its consumer-facing apps and focused on offering its machine learning algorithms to publishers and hedge funds.Prismatic was produced by Prismatic, Inc., a United-States-based software company founded in 2010 by Bradford Cross and Aria Haghighi and headquartered in San Francisco, California.

Salix OS

Salix OS is a multi-purpose Linux distribution based on Slackware.

Sylpheed

Sylpheed is an open-source e-mail client and news client licensed under the GPL. It provides easy configuration and an abundance of features. It stores mail in the MH Message Handling System. Sylpheed runs on Unix-like systems such as Linux or BSD, and it is also usable on Windows. It uses GTK+.In 2005, Sylpheed was forked to create Sylpheed-Claws, now known as Claws Mail. As of 2015, both projects continue to be developed independently.

Sylpheed is the default mail client in Lubuntu, Damn Small Linux and some flavours of Puppy Linux.

Tails (operating system)

Tails or The Amnesic Incognito Live System is a security-focused Debian-based Linux distribution aimed at preserving privacy and anonymity. All its incoming and outgoing connections are forced to go through Tor, and any and all non-anonymous connections are blocked. The system is designed to be booted as a live DVD or live USB, and will leave no digital footprint on the machine unless explicitly told to do so. The Tor Project has provided financial support for its development.

Transport Neutral Encapsulation Format

Transport Neutral Encapsulation Format or TNEF is a proprietary email attachment format used by Microsoft Outlook and Microsoft Exchange Server. An attached file with TNEF encoding is most often named winmail.dat or win.dat, and has a MIME type of Application/MS-TNEF.

The official (IANA) media type, however, is application/vnd.ms-tnef.
